Abstract
Hemicentin has come a long way from when it was first identified in C. elegans as him-4 (High incidence of males).The protein is now a recognized player in maintaining the architectural integrity of vertebrate tissues and organs.Highly conserved hemicentin sequences across species indicate this gene’s ancient evolutionary roots and functional importance. In mouse, hemicentin is liberally distributed on the cell surface of many cell types, including epithelial cells, endothelial cells of the eye, lung, and uterus, and trophectodermal cells of blastocyst. Recent discoveries have uncovered yet another vital purpose of hemicentin 1. The protein also serves a unique function in mitotic cytokinesis, during which this extracellular matrix protein plays a key role in cleavage furrow maturation.Though understanding of hemicentin function has improved through new discoveries, much about this protein remains mysterious.
